Jeff,
First of all, I must say, that in addition to my off air signals, I do have a satellite dish (the Canadian ExpressVu system), although for some reason, I like watching tv the old fashioned way (i.e. off the antenna, if I can get even a remotely watchable signal--I know, I am weird (LOL))
As for where Tweed is located, it is approximately mid way between Toronto and Ottawa (if you have a map which shows southern Ontario, my nearest major city would be Belleville, if it is shown--if not, Kingston--I am about 30 miles north of Belleville, and about 50 miles north-west of Kingston).
As for my local signals (off-air), Belleville has two channels, an educational one and a french. My only other two which come in completely clearly all the time, are my local CBC affilliate out of Kingston, and my local CTV affiliate which is a repeater of the Ottawa CTV--the repeater is in a community called Deseronto. Other than that, my primary US stations are the ABC, CBS and PBS affilliates out of Watertown, NY, about 60 miles from me. Other than that, I can usually get a couple of the Rochester stations, and the ABC and PBS out of Syracuse, so I guess the reception isn't really that bad. If you are used to watching cable calibre reception from a big city, my reception would be considered poor, but on the other hand, with the lack of strong stations filling up the dial, it makes it interesting for tv DX.
